Description

Bei aus Quarzglas hergestellten Ultraviolettbestrahlungslampen ist nach einer gewissen Brennzeit eine Aufarbeitung erforderlich. Zu diesem Zwecke muß der Brenner auseinandergeschnitten werden, wobei im allgemeinen in-_ folge der Schwierigkeiten, die mit der Entfernung der in Quarzkapillaren eingeschmolzenen Stromzuführungsdrähte verbunden sind, ein Verlust von. Quarzmaterial eintritt, ein Mangel,In the case of ultraviolet radiation lamps made of quartz glass, after a certain amount of time Burning time requires work-up. For this purpose, the burner must be cut apart be, being generally in-_ a consequence of the difficulties encountered with removal connected to the power supply wires fused in quartz capillaries Loss of. Quartz material enters, a defect,

ίο dessen Beseitigung mit Rücksicht auf den hohen Preis des Quarzglases erstrebenswert ist.ίο its elimination with regard to the high Price of the quartz glass is worth striving for.

Die Erfindung besteht nun darin, daß der Draht mittels .eines Lichtbogens, insbesondere eines Gleichstromlichtbogens, verdampft wird:.The invention now consists in that the wire by means of an arc, in particular of a direct current arc, is vaporized :.

Der Draht wird z. B. an 'eine Gleichstromquelle von 220 Volt derart angeschlossen, daß der positive Pol der Stromquelle fest mit dem leinen Ende des Drahtes verbunden und dem anderen Drahtende eine an dem negativen Pol der Stromquelle liegende Elektrode aus schwer schmelzbarem Material, z. B. Wolfram, gegenübergestellt wird. Beim Einschalten der Stromquelle verdampft dann der Lichtbogen den Draht in Bruchteilen einer Sekunde, wobei eine geringe, um den Draht befindliche Quarzglasschicht mit fortschmilzt, so daß nach der Aufarbeitung des Brenners leicht ein neuer Wolframdraht eingeschoben und eingeschmolzen werden kann. Es können also alle Quarzteile des Brenners wieder verwendet werden.The wire is z. B. to 'a direct current source of 220 volts so connected that the positive pole of the power source is firmly connected to the linen end of the wire and the other end of the wire an electrode lying on the negative pole of the power source made of difficult-to-melt material, e.g. B. tungsten, is contrasted. When switching The power source then vaporizes the arc to the wire in a fraction of a second, leaving a small amount to the wire The quartz glass layer that is located melts away with it, so that after the burner has been worked up a new tungsten wire can easily be inserted and melted down. It can so all quartz parts of the burner can be reused.

Bei Verwendung eines Hochfrequenzlichtbogens wird das Quarzrohr ohne festen Anschluß zwischen den beiden Elektroden angeordnet. Das Verdampfen erfolgt von beiden Seiten gleichzeitig.If a high-frequency arc is used, the quartz tube becomes without a fixed connection arranged between the two electrodes. Evaporation takes place from both sides at the same time.

Das Verdampfen kann in freier Atmosphäre oder auch im Vakuum, zweckmäßigerweise gleich im Brenner, vor sich gehen.Evaporation can take place in a free atmosphere or in a vacuum, expediently right in the burner.

In der Zeichnung ist beispielsweise eine Anordnung zum Ausbrennen des Drahtes wiedergegeben. Der in das Quarzrohr 1 eingeschmolzene Wolframdrait 2 ist an dem einen Ende in der Klammer 3 eingeklemmt und über meinen Widerstand 4 von etwa 20 bis Ohm mit dem positiven Pol einer Gleichstromquelle von 220 Volt Spannung verbunden. An dem negativen Pol der Gleichstromquelle ist eine Wolframelektrode 5 angeschlossen, die gegenüber. dem anderen Ende des Drahtes angeordnet ist. Nach Einschalten des Schalters 6 ist der Draht 2 im Bruchteil einer Sekunde verdampft.In the drawing, for example, an arrangement for burning out the wire is shown. The tungsten wire 2 melted into the quartz tube 1 is on one side End wedged in the bracket 3 and over my resistor 4 from about 20 to Ohm connected to the positive pole of a direct current source of 220 volts. A tungsten electrode 5 is connected to the negative pole of the direct current source, the opposite. the other end of the wire is arranged. After switching on of the switch 6, the wire 2 is vaporized in a fraction of a second.
